Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed July 6, 1905. Serial No. 268,561.

To a whom, it "may concern:

Be it known that I, KNUD H. KNUDSVIG, a citizen of the United States, residing at Buxton, in the county of Traill and State of North Dakota, have invented certain new and useful Improvements in Belt-Guides3 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to means for guiding the belts of machinery, and is especially intended for use upon a traction-engine to guide the long belt extending from same and driving a threshing-machine at some distance, so that the long belt is often disengaged from the drive-pulley by the wind or i by the jar arising from uneven feeding to the threshing-machine.

The main object is to provide an efficient and convenient belt-guide for such machinery. This and other objects I attain by the novel construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a sectional rear elevation of the front portion of a traction-engine with my belt-guide applied. to it. Fig. 2 is a top view of the belt-guide only, and Fig. 3 is a partlysectional rear view of Fig. 2.

Referring to the drawings by referencenumerals, l designates the boiler, 2 the smokestack, 8 the crank-shaft, and 4 the drive-pulley, of a common traction-engine, while 5 is the shaft, and 6 the pulley, of the threshingmachine driven by the belt 7 from the pulley 4. The latter pulley may thus be considered as located rearward of the guiding-rollers 8 and 9, while the pulley 6 is forward of the rollers-perhaps thirty to fifty feet away.

The guide-rollers 8 and 9 revolve on studs 10, which, as best shown to the right in Fig. 3, are adjustably held in slots 11 of framearms 12 13 by having each a nut 14, serving as a shoulder below the arm, and a nut 15 above the arm for tightening the stud at any point in the slot. The studs are thus adjustable upward when the rollers wear downward. and are adjustable to and from each other and the engine, so as to suit belts of different widths and. location upon the engine-shaft.

The frame-arm 12 is bifurcated into two legs, securable by bolts 16 to the side of the boiler or smoke-box thereof. I11 Fig. 1 it is shown as secured to the bolts holding one of the bars 17, which project forward of the smoke-box to support a watertank. (Not shown.) To the arm or bracket 12 is pivoted at 18 the arm 13, so that the latter arm rests normally upon the supporting-point 19, on which it is held. by gravity and by the lower end of a latch 20, pivoted to the bracket 12, and when the belt is to be thrown off or repaired or the engine isto go between the grain-stacks or near other objects the arm 13, with its roller 9, is thrown upward, resting against the boiler, as shown in dotted lines 9 and 13 in Fig. 1, in which position it is further secured by turning the higher end of the latch 20 against it.

The slots 11 for horizontal adjustment of the rollers may be dispensed with where the width of the belt is known and the distance of the pulley 4 from the boiler is either known or adjustable.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. A belt-guide comprising abracket adapted to be fixed to an object near the belt, a revoluble guiding-roller on a stud secured in the fixed bracket, an arm pivoted to the bracket and having a revoluble guiding-roller normally disposed parallel to the first-mentioned roller, and locking means for holding said arm in lowered and in raised position substantially as and for the purpose set forth.

2. A belt-guide comprising a bracket securable to an object near the belt, a revoluble guiding-roller carried thereby, an arm pivoted to the bracket and having a revoluble guiding-roller normally disposed. parallel to the first-mentioned roller, said rollers being adjustable to and from each other and to and from the object supporting the bracket.

In testimony whereof I affix my signature in presence of two witnesses.

KNUD H. KNUDSVIG.
